Evaluation of the effect of carnosine, its novel derivative trolox-carnosine and trolox in a pre-clinical study focussing on the regulation of immunity

European Pharmaceutical Journal, 2016
The neuroprotective or neurotoxic effects of the products of the kynurenine pathway of tryptophan metabolism highly depend on the action of kynurenine-3-monooxygenase (KMO).

Maternal and infant gut microbiome

iMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Kynurenine mediates the chemotherapy-induced intestinal toxicity through modulation of gut microbiota

Nature Communications
Chemotherapy-induced intestinal toxicity is a major dose-limiting complication, but the underlying mechanisms linking systemic metabolism to localized gut damage are poorly understood.

Targeting the intratumoral microbiota to overcome cancer immunotherapy resistance

Interdisciplinary Medicine, EarlyView.
This review delineates the mechanisms of intratumoral microbiota in cancer immunotherapy resistance, and offers strategies for microbiota‐targeted precision immunotherapy. Abstract Cancer remains a significant global health threat. The tumor microenvironment (TME) is a sophisticated ecological niche that exerts a pivotal effect on treatment outcomes ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

Circadian rhythms and chronotherapy in Alzheimer's disease: Mechanisms and therapeutic implications

Neuroprotection, EarlyView.
Circadian dysregulation contributes to Alzheimer's disease through sleep disruption, clock‐gene dysfunction, neuroinflammation, impaired proteostasis, and metabolic imbalance. These alterations promote cognitive decline and disease progression, while circadian biomarkers and chronotherapeutic interventions offer opportunities for precision diagnosis ...

Post‐Omicron cognitive decline is largely reversible: Two‐year multicenter cohort study of domain‐specific outcomes in hospitalized patients

Neuroprotection, EarlyView.
Earlier variants of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV‐2), including the original strain, Alpha and Delta, were linked to significant and persistent cognitive impairment. The long‐term cognitive impact of Omicron infection, however, has remained uncertain. This study shows that post‐Omicron cognitive decline is largely reversible,

Phthalate Metabolite, Mono(2‐Ethyl‐5‐Hydroxyhexyl) Phthalate (MEHHP), Promotes Uterine‐Fibroid–Associated Phenotypes in Myometrial Stem Cell‐Derived 3D Organoids

Environmental Toxicology, EarlyView.
ABSTRACT This study investigates how phthalate exposure contributes to uterine fibroid (UF) development by studying the effects of the Mono‐(2‐ethyl‐5‐hydroxyhexyl) phthalate (MEHHP), a metabolite of Di(2‐ethylhexyl) phthalate, on myometrial stem cells (MMSCs).

Gut microbiota dysbiosis and Long COVID susceptibility in chronic kidney disease

VIEW, EarlyView.
This study investigated gut microbiota dysbiosis and its association with Long COVID susceptibility in 224 hemodialysis patients. We found that 35.3% of patients developed Long COVID, characterized by neurological symptoms and elevated inflammatory markers, accompanied by significant gut microbiota alterations including enriched proinflammatory taxa ...
